Reported on TBB a couple of weeks ago. It has been discussed in a few threads on here I think when it first came out. Some detail still missing from exactly how it will work but certainly looks interesting.
It has the potential to be cheaper than the current system and there are a few people on here who had already upgraded under the current scheme with 3 year business contracts. The big benefit appears to be that if one person in a street upgrades then it becomes standard FTTP for everyone else.
